Simply cut and paste the below code into the <body> section of your page. It
contains a form with one box that is checked for "email validity". You can add in more form elements into the form, as you would with any other form.

<form name="validation" onSubmit="return checkbae()">
Please input a valid email address:<br>
<input type="text" size=18 name="emailcheck">
<input type="submit" value="Submit">
</form>
<script language="JavaScript1.2">

var testresults
function checkemail(){
var str=document.validation.emailcheck.value
var filter=/^([w-]+(?:.[w-]+)*)@((?:[w-]+.)*w[w-]{0,66}).([a-z]{2,6}(?:.[a-z]{2})?)$/i
if (filter.test(str))
testresults=true
else{
alert("Please input a valid email address!")
testresults=false
}
return (testresults)
}
</script>
<script>
function checkbae(){
if (document.layers||document.getElementById||document.all)
return checkemail()
else
return true
}
</script>

var reg = /^([A-Za-z0-9_-.])+@([A-Za-z0-9_-.])+.([A-Za-z]{2,4})$/; var address = document.form1.email.value; if(reg.test(address) == false) { alert('Invalid Email Address'); document.form1.email.focus(); return false; }
